Product Description
OT-139 Carbon Monoxide Detector
The compact and easy-to-use mini CO detector. With a single charge, it provides up to 15 days (360 hours) of usage in standby mode, meeting all long-term CO monitoring needs. It is suitable for various scenarios such as home, travel, camping, driving, etc.
How to Check If Your OT-139 Is Functional:
1. Cigarette Smoke Test:
Place the back ventilation holes of the product close to cigarette smoke and close enough to avoid gas diffusion.
2. Sealed Container Test:
- Burn paper or material completely in a sealed container to create a low-oxygen environment.
- Place the back ventilation holes of the product close to the container immediately after burning to detect CO.
Attetion:
- Ensure preheated in air free of CO.
- External factors like ventilation or air currents may dilute CO, affecting detection accuracy.
Features:
- Compact size and lightweight, equipped with a lanyard and stand for versatile placement in different environments.
- Green breathing light flashes in standby mode.
Charging:
- Extended standby time: 15 days (360 hours) in standby mode.
- Type-C charging time: 2-3 hours.
Specifications:
- Sensor: Electrochemical.
- Alarm Modes: Audible & Visual (when enabled).
- Audible: 90 dB, increasing in frequency with rising CO levels.
- Visual: Red breathing light and flame icon on the screen.
- Detection Range: 0-1000 ppm.
- Response Time: T ≤ 30 seconds.
- Operating Conditions: -4°F to 122°F (-20°C to 50°C), <90% RH (non-condensing).
Note:
When turning the device on or off, please press and hold the power button for 3-4 seconds until the progress bar reaches the end to complete the process before releasing. There is a protective film on the screen; please remove it before use.
